9. Video Checking Features
OmniTek XR has the ability to display real-time video status information and to detect and
count various types of error. This status information and associated error counts are
displayed in the Video Status window, which may be called up either from the Window
menu or by clicking on the Video Status icon on the main (Window) toolbar.
Note: The aspects of the video that are checked depend both on the video format and on which
additional packages are included in the OmniTek XR system that is being used.
Video Status Display
The Status window shows a range of information about the video being analysed,
organised into a collapsible hierarchy that allows the user to select what is displayed
according to their particular requirements. Sections of this hierarchy can be opened (and
closed) by clicking on the +/- symbols displayed alongside the various headings that
define the sections of the hierarchy – in the same way that clicking in Window Explorer
opens or closes the folders within its file hierarchy.
Individual ‘leaves’ of the hierarchy (and sections) can also be hidden from display by
right-clicking on the item and taking the option to Hide item from the submenu that
appears. Moreover, if all the leaves within a particular segment of the hierarchy are
hidden, that segment will also be hidden. (The context menu that appears on right-
clicking also includes options that allow sections of the menu to be re-‘expanded’ after
being hidden.)
There is also the option of a ‘Flat view’ (selectable from the Options menu) in which the
same selection of details are seen but with only the section headings to indicate the
presence of other parts to the hierarchy. In this view there are no +/- symbols on which to
click to expand or collapse parts of the hierarchy but the context menu remains available
to hide or re-expand parts of the display as required.
Another option is to show timelines that indicate graphically the rate at which different
types of error occur by showing the number of errors experienced in a chosen sample
time as a proportion of the total number of samples. These timelines are both selected
and configured from the Options menu (see page 88)
As shown in the example displays below, the ‘values’ associated with particular status
items are often shown coloured green, orange/brown or red to make it immediately clear
whether the value currently being reported is OK (green) or incorrect in some way but not
being used (orange/brown) or incorrect and being used (red). In addition, the heading line
of unexpanded sections (together with the main ‘Video’ heading) may be marked with a
cross in a red circle to indicate that at least one error has been detected among the items
of that section. This provides a simple and effective way of, firstly, alerting the user to the
fact that an error has occurred and, secondly, guiding the user to the relevant part of the
status display.
Note: In all, an extensive amount of information can be displayed. If simply opening and closing
sections of the hierarchy doesn’t give you the display you need, you can ‘filter’ the
information down to just those items you are interested in (and save the filtering you
select). This is described in the section starting on page 119.
